GC columns are of two types; packed column and capillary column. Capillary column carries the gas through a central aperture which is unimpeded through the entire length of column. In general, capillary columns are made longer to produce more theoretical plates. This also helps in band dispersion eventually narrowing the peaks and resulting in high resolution.

Other Notes

This is a TightSpec column, which conforms to within +/- 6 mm of its stated length.

Application

Empty column may be used for packing adsorbents for temperature-programmed desorption (TPD) instrumentation.
